Problems solved by technology
This kind of wrench has poor practicability, requires a lot of force during disassembly and assembly, and is easy to slip off, causing injury to the operator. Moreover, one type of crescent wrench generally only corresponds to one type of four-slot lock nut. High cost; What's more difficult is that for the relatively closed slotted round nut installed in a narrow space, due to the narrow operating space, it is inconvenient to use conventional tools to screw it, and it is very difficult to disassemble it

Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings.
[0025] This embodiment provides a disassembly tool for four-slot lock nuts, but is not limited to four-slot lock nuts.
[0026] Such as figure 1 , 2 As shown, the dismounting tool of the four-slot lock nut of the present invention includes a main slide rail bottom plate 1, a left slide plate 2, a right slide plate 3, a left lock bolt 4, a right lock bolt 5, a left flange lock nut 6, Right flange lock nut 7, four-slot lock nut 8, thread adjustment clamp 9, thread adjustment telescopic tube 10 and internal thread adjustment fixing block 11.
[0027] In the specific production, by using a cold-rolled plate with a length of 500mm, a width of 30mm, and a thickness of 6mm, the central symmetrical laser cutting is used, and a long hole with a width of 6mm is cut off as the slide rail of the bottom plate to make the main slide. Rail bottom plate 1. Utilize a 250x25x4mm col...

The invention discloses a tool for disassembling and assembling a slotted lock nut, which comprises a main slide rail base plate, a left slide plate, a right slide plate, a screw adjusting chuck, a thread adjusting expansion tube and an internal thread adjusting fixing block, and the main slide rail base plate is a long strip There is a long through groove as a chute on it, and there are matching through grooves on the left slide and the right slide. The left slide and the right slide are connected to both sides of the bottom plate of the main slide rail by sliding. Internal thread adjustment and fixing blocks that can be screwed into the thread adjustment chuck are respectively arranged on the ends, and internal thread adjustment and fixing blocks that can be screwed into the thread adjustment expansion tube are respectively arranged on both ends of the thread adjustment telescopic tube, and the thread adjustment telescopic tube The center of the center is fixedly connected with the center of the main slide rail bottom plate, and relative rotation can take place between the two. The tool of the invention has a large torque, is not easy to slip off, is convenient to implement, has good clamping stability for the disassembly and assembly of the four-slot lock nut, and has a large screwing force and is more applicable to deep grooves and narrow space areas.
Description
technical field [0001] The invention relates to a nut dismounting tool, in particular to a slotted locking nut dismounting tool. Background technique [0002] In the known field of disassembly and assembly of large four-slot lock nuts, there are many types of slotted lock nuts, British and American standards, it is impossible to purchase a unified disassembly tool, and the use of functional areas is diverse, and the corresponding disassembly positions are inconvenient and not easy to solve. [0003] At present, a crescent wrench is generally used to fasten and loosen the four-slot lock nut. The crescent wrench is a hook at one end hooking a groove of the four-slot lock nut, and the nut is tightened or disassembled by rotation. This kind of wrench has poor practicability, requires a lot of force during disassembly and assembly, and is easy to slip off, causing injury to the operator. Moreover, one type of crescent wrench generally only corresponds to one type of four-slot loc...
